15.4. Configure the /etc/ssh/sshd_config file
StrictModes yes

The option StrictModes specifies whether ssh should check user's
permissions in their home directory and rhosts files before accepting login.
This option must always be set to yes because sometimes users may
accidentally leave their directory or files world-writable.

3.14 - I copied my public key to authorized_keys but public-key
authentication still doesn't work.

Typically this is caused by the file permissions on $HOME, $HOME/.ssh or
$HOME/.ssh/authorized_keys being more permissive than sshd allows by default.

In this case, it can be solved by executing the following on the server.

$ chmod go-w $HOME $HOME/.ssh
$ chmod 600 $HOME/.ssh/authorized_keys
$ chown `whoami` $HOME/.ssh/authorized_keys

If this is not possible for some reason, an alternative is to set StrictModes
no in sshd_config, however this is not recommended.
